How Accurate is Sense? Summary of Sense Accuracy Measurements vs Utilities

I just looked at 2022 annual usage and generation from Sense and our local utility bill. The total usage (11413 kwh) and solar generation (8772 kwh) are much higher from Sense than from the utility (usage 8583 kwh and generation 6096 kwh), but the net usage is reasonably close within 154 kwh (. Given the accuracy of Sense as noted in this discussion thread, any suggestions on why the large difference in the annual numbers? As near as I can tell, I’m comparing Jan to Dec 2022 in both cases. Also, the Enphase solar energy summary for 2022 shows 9200 kwh generated. Any suggestions or thoughts about these differences?
